Students’ self‐assessment in law: Report of a pilot project
No full textThe pilot study reported here was a one‐off study about self‐assessment by students of a law assignment (a problem in the law of Tort). The project was conceived as a result of concern about too much assessment/marking and its effect on staff time (and research and other scholarly activities) and also as a result of discussions the author had with his faculty colleagues and other colleagues outside his institution. This report focuses on the following issues: definition and problems of self‐assessment, aims of the study, review of the literature, method of study, findings and discussion of the findings
Indications for emergency abdominal surgery in Cape Coast, Ghana
No full textBackground: Emergency abdominal surgery continues to form a major workload of the general surgeon. As a result of variation of causes, there is need to revisit and review the pattern of presentation, management and outcome. There had been previous studies from Korle Bu Teaching hospital and Komfo Anokye Teaching Hospital both in Ghana, but this is from Cape Coast Teaching Hospital (CCTH), Central Region, Ghana. The objective is to determine the pattern of presentation and indications for surgery in patients who had emergency abdominal surgical operation in CCTH.Methods: All patients who had emergency abdominal surgical operations at the Cape Coast Teaching Hospital from 1st January 2011 to 25th October 2012 were retrospectively reviewed.Results: Four hundred and eleven patients had emergency abdominal operation over a period of 22 months. The mean age at presentation was 36.3 years (SD 19.3). Male to Female ratio was 2.3:1. Intestinal obstruction was the commonest indication for surgery followed by appendicitis and typhoid ileal perforation. Obstructed abdominal wall hernia was the commonest cause of intestinal obstruction.Conclusions: Early reporting in hospital and access to hernia repair will reduce the morbidity and mortality known to be associated with this condition.</jats:p
Differential association theory and juvenile delinquency in Ghana's capital city -Accra: The case of Ghana borstal institute
No full textCurrent sociological theories argue that, delinquency results from economic and family relational problems. Unable to have their parents meet their material needs, children turn to all sorts of activities, many of which eventually lead to delinquent acts. Other theories focus on the role of peer relationships in determining deviancy. Using Edwin Sutherland's differential association theory, this study explores the notion that, delinquency in inmates of the Ghana borstal institute is a reflection of the peer groups/friendship relations they hanged out with. Data for the study were collected from the Ghana borstal institute, a correctional institution for reforming juvenile offenders with structured questionnaire. The findings point to the presence of Differential Association at the onset of inmate's delinquent behaviours though circumspection is recommended in the attempts to validate differential association as the study was carried out on institutionalized, verified group of delinquent juveniles. The close relationship between differential association and delinquency may not be present in noninstitutionalized juvenile offenders
Effects of fluorine on the structure of fluorohydroxyapatite: a study by XRD, solid-state NMR and Raman spectroscopy
No full textFor the first time we observed well-resolved Ca(I) and Ca(II) signal changes in fluorohydroxyapatites with different fluorine contents by solid state NMR. The experiment results show that fluorine ions perturb the chemical environment of Ca(II) ions andOH(-) ions more than phosphorus tetrahedra and Ca(I) ions.http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000346003300005&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701Materials Science, BiomaterialsSCI(E)[email protected]
New technology in health education

Purpose
The purpose of this paper is to investigate undergraduate nursing students’ use of mobile learning (m-learning) and the factors contributing to their use of m-learning.
Design/methodology/approach
In total, 586 nursing students from three universities in Ghana participated in this study. Survey questionnaires were used to collect data. Descriptive statistics, sample t-test and multiple regression were used to analyze the data.
Findings
The research found that most students owned smartphones. Mobile technology was mainly used for doing homework. The result indicates that gender differences exist in terms of perceived usefulness of m-learning. In addition, age differences exist with regard to the perceived ease of use of m-learning. Furthermore, students showed positive attitudes toward the use of technology. Finally, perceived usefulness and attitudes toward the use of technology predicted students’ intention to use m-learning.
Originality/value
Despite the abundance of research on nursing education in other countries, there is a lack of research on nursing students’ use of m-learning and factors influencing their implementation of m-learning in higher learning institutions in Ghana. This study is important because it provides a clear description of nursing students’ use of m-learning and factors affecting their use in schools. Also, the author suggests that information from this study assists school administrators and nursing educators to understand students’ positions regarding m-learning in classroom.

Patient age, diagnosis, hemoglobin level and sex in the optimal management of blood and blood products
No full textBlood is a critically important human tissue, and for over a century, blood transfusions have saved the lives of countless patients. However, blood is often in short supply, and the cost of screening donated blood for immune compatibility and an ever-increasing number of blood-borne pathogens keeps rising. As healthcare systems search for ways to cut costs, it is appropriate to search for safe and effective ways to conserve blood and blood products.
Aim: This study will examine the following questions:
1. What is the relationship between the diagnosis and the amount of packed red blood cells (PRBC) used for patients with specific conditions?
2. What is the benefit of the transfusion for the patient in terms of the post transfusion hemoglobin and the clinical outcome?
3. Is there an association between patient age, diagnosis and the amount PRBC used? 4. What common diagnoses usually result in patients being given transfusions, and what is the clinical benefit of those transfusions?
The overall aim of this study is to identify conditions in which blood may be conserved, without affecting patient clinical outcomes.
Methodology: All patient data were collected from the Meditech database of the Queen of Valley Medical Center (QVMC), with the permission of the Blood bank supervisor and Medical Laboratory Director.
Results: Data was collected on 504 PRBC-transfused patients with various clinical conditions, who had critical pre-transfusion hemoglobin levels. Post-transfusion hemoglobin levels were examined at the time of patient discharge or patient death. A control cohort of twenty patients with the same conditions and critical hemoglobin levels but were not transfused due to religious or other reasons was also analyzed. Patients with acute kidney failure (AKF) and acute post-hemorrhagic anemia (APA) had better outcomes when they were transfused. The importance of any single transfusion to relapsed acute myeloid leukemia patients (AL) was difficult to assess as they are constantly being transfused. Patients with anemia of unknown causes (AU) and hemoglobin levels between 7-8g/dl did not require transfusion for survival.
Conclusion: Low hemoglobin levels alone should not automatically trigger transfusions. Disease type, patient age, and other factors should be taken into consideration.Ph.D.Includes bibliographical reference

Heating Effect of Mesa-type Intrinsic Josephson Junction Stacks Using Pulse Current Measurement
No full textAbstractWe experimentally investigated the self-heating effect of large-scale mesa-type intrinsic Josephson junction stacks in the single-crystal Bi-2212 using pulse current measurement techniques. In addition, the effects of contact resistance between the electrodes and top of the mesa were studied. The current-voltage (I-V) characteristics obtained by using the pulse measurement technique showed significantly improved voltage suppression compared to the dc measurement. Furthermore, we proposed a new pulse waveform. Using the proposed waveform, I-V characteristics could be obtained with heat generation at the contact resistance only. It is revealed that the heating at the contact resistance had a significant effect on the I-V characteristics
Effect of Pr Additions to Li-doped Bi2212 Bulk Superconductors Sintered at Low Temperature
No full textAbstractThe physical properties study of the Bi2Sr2CaCu2Oy (Bi2212) ceramics samples sintered at low temperature has been carried out by measurement of electrical resistance and powder X-ray diffraction (XRD). The effects of Pr doping on the formation process of the Bi2212 phase, and its structural and superconducting features were studied. The samples were prepared by a solid-state reaction method from oxides and carbonate powders. The samples with nominal composition Bi2.12Sr1.90Ca1.02Cu1.96Li0.15Cl0.15Oy added with praseodymium oxide (Pr2O3) were sintered in air at 710°C. The Pr2O3 addition ranging between 0.1mass% and 1.2mass% promotes the formation of the Bi2212 phase in low temperature synthesis. The full-width at half maximum (FWHM) value of the (200) and (0010) XRD peaks is slightly decreasing in the samples for low level doping and reaches a minimum around 0.6mass%. The maximum zero resistance temperature (Tc) is observed at 82.5K for the sample with 0.6mass% Pr2O3 addition by sintering even at 710°C, which is about 150°C lower than that of the non-added Bi2212 phase
